False -3 and 3 because 3×3=9 the same for -3.

The answer is False. The square root of 9 is equal to 3 not -3. A square root of 16 is indeed 4 because it is a number that can be divided equally into 16. For example another square root for 16 is 2. 9 can only have 1 square root because no other number divides into it equally and the 1 square root is 3.

Anettt [7]

The answer is an average rate of change of 110 more dollars in her account per week. You find this by first subtracting the starting amount of 250 from the end amount of 800 that equals 550. then you divide that number by five, the number of weeks, to get the average rate of change.
